Which of the following is a common method for proving loyalty in gang membership?

The method known as "jumping in" or "blood in/blood out" is a well-documented practice within gang culture that serves as a rite of passage for proving loyalty and commitment to the gang. This process often involves the potential member undergoing a form of initiation, which can include physical violence or other significant measures intended to demonstrate their willingness to endure hardship for the sake of the gang.

This initiation signifies a lifelong commitment, whereby "blood out" implies that leaving the gang is often not an option without dire consequences. It is a clear marker of loyalty within the gang structure, as these methods convey the seriousness of the commitment being made.

On the other hand, methods such as correcting fellow members' mistakes, participating in community service, or attending educational workshops do not carry the same weight of loyalty and commitment to gang culture, which typically values toughness and resilience over non-violent contributions to society. Thus, the initiation rituals of "jumping in" or "blood in/blood out" are central to gang loyalty.
